14 DAY TRIAL // We'd have expected E Ink to be the one to show us a new color e-paper screen, but that didn't happen. Instead, Fuji Xerox Co Ltd brought out a model at on the opening day of SID 2012 (June 3, 2012, in Boston, US).
There are three layers to this color e-paper. One of them is the “visible” one, the second is an “invisible” layer and the third is a while-colored layer set between them (it can provide a blank screen when required).
Magenta red and cyan particles produce the colors by mixing together in uneven amounts. The full range of colors on the finished panel should be wider than that of regular newspapers.
According to Tech-On, the prototype at SID 2012 displayed colors by moving red and cyan particles up and down between the layers separated by the white one.
The native resolution was 600 x 800 pixels and the diagonal of 5 inches.
